Distributed network address discovery in non-uniform networks

Abstract

Distributed network address discovery in non-uniform node networks can be performed. Regarding a client request for a service, network management component (NMC) can determine a network address space associated with a client based on a network identifier associated with the client or a node identifier. NMC can determine a group of candidate nodes (CN group) from a group of nodes based on network addresses associated with nodes of the node group and the network address space. NMC can determine a group of available candidate nodes (ACN group), from the CN group, available and able to process the request and perform the service based on operational statuses associated with the nodes of the CN group or services associated with those nodes. From the ACN group, NMC can determine a ranked list of network addresses associated with available nodes that can process the request based on defined service performance criteria.
